Defensive publication

ABSTRACT

COMPOSITIONS OF STABILIZED OXIDIZED-POLYETHYLENE ARE PROVIDED WHICH HAVE IMPROVED COLOR STABILITY WHEN REACTED WITH ALKALINE REAGENTS. THE IMPROVED COLOR STABILITY IS OBTAINED BY INCORPORATING INTO THE OXIDIZED-POLYETHYLENE A STABILIZING AMOUNT OF A PHOSPHORUS-CONTAINING COMPOUND WHICH IS (1) AN OXY ACID OF PHOSPHORUS IN WHICH THE PHOSPHORUS ATOM HAS AN OXIDATION STATE OF +1 OR +3; (2) AN ALKALI METAL SALT OF AN OXY ACID AS DESCRIBED IN (1) WHEREIN THE ALKALI METAL IS LITHIUM, SODIUM, OR POTASSIUM; OR (3) A REACTION PRODUCT OF AN OXY ACID AS DESCRIBED IN (1) WITH AMMONIA, MORPHOLINE, OR A PRIMARY, SECONDARY OR TERTIARY AMINE HAVING 1 TO 6 CARBON ATOMS.

PUBLISHED MARCH 14, 1972 T896021 STABILIZED OXIDlZED-POLYETHYLENE COMPOSITIONS Daniel L. Edwards, Jr., and Sarah J. Dickerson, both of P.(). Box 511, Kingsport, Tenn. 37662 Continuation of application Ser. No. 779,245, Nov. 26, 1968. This application Aug. 14, 1970, Ser. No. 63,951 Int. Cl. (308i 45/46 US. Cl. 26029.6 MP N0 Drawing. 15 Pages Specification Compositions of stabilized oxidized-polyethylene are provided which have improved color stability when reacted with alkaline reagents. The improved color stability is obtained by incorporating into the oxidized-polyethylene a stabilizing amount of a phosphorus-containing compound which is (1) an oxy acid of phosphorus in which the phosphorus atom has an oxidation state of +1 or +3; (2) an alkali metal salt of an oxy acid as described in (1) wherein the alkali metal is lithium, sodium, or potassium; or (3) a reaction product of an oxy acid as described in (l) with ammonia, morpholine, or a primary, secondary or tertiary amine having 1 to 6 carbon atoms.
